Need .NET architecture advice?
Our enterprise Microsoft stack team can review your codebase or scope your new .NET build in a technical session.
Cost factors of .NET development depend on the target platform and scale:
- A single web API vs. a full enterprise application with a Blazor/MAUI front end.
- Cloud-native architecture on Azure vs. on-premise deployment.
- Integration with Microsoft ecosystem tools (SharePoint, Dynamics 365, Power BI).
- Compliance and security hardening requirements.
- Ongoing DevOps and support needs.
Budget Range: Starts at $1,000 for core business applications, scaling with complex enterprise architecture and high-throughput integrations.
Timeline depends on complexity:
- 6–10 weeks: Basic web APIs and internal tools.
- 3–5 months: Mid-complexity applications with Azure integration and reporting.
- 4–8 months: Enterprise .NET systems with Dynamics 365 or SharePoint integration.
We build on the current .NET ecosystem, not legacy .NET Framework unless required for compatibility:
- Core: C#, ASP.NET Core, .NET MAUI, Blazor, Entity Framework.
- Databases: SQL Server, PostgreSQL, MySQL.
- Cloud: Microsoft Azure (App Services, Functions, Azure SQL).
- Integrations: SharePoint, Dynamics 365, Power BI, and REST/SOAP APIs.
